To aZZ whom it may concern:

Be it known that I, JAMES H. SKITT, a subject of the King of England, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Circulating Rotary Dyeing-Machines, of which the following is a specification.

The object of the invention is to provide a circulating rotary dyeing machine, which, broadly stated, comprises a rotary carrier divided into compartments and having a: circulating medium located centrally of the carrier whereby the dye liquor will be cir- 3 culated from the carrier exterior through. certain compartments to the center of the carrier and from the carrier center through other compartments to the exterior of the carrier.

- Fig. 2 is a plan view of the driving end of the machine, Fig. 3 is a vertical sectional view through Fig. 1. Fig. 4 is a horizontal sectional view taken through the drive gearing, and Fig. 5 is a vertical sectional view taken through Fig. 3 on the line 55 thereof, and showing the circulating plan.

The invention comprises a vat for containing the dye liquor, and consists of side walls 2 and semi-circular bottom 3, and this vat is provided with a cover 4 which includes the side walls 5, upper wall 6, and doors 7 in the latter. The cover is suitably supported on the upper edges of the vat. Journal boxes or bearings 8 are mounted on the upper edges of the sides and in these are journaled the opposite ends of a shaft 9. J ournaled on opposite ends of the' shaft 9 are flanged hubs 10 which are secured concentrically to disks 12 and 14 forming the end plates of the carrier. At regular intervals between the said disks 12 and 14 are secured radial partitions 15 dividing the carrier into compartments A, B, C, D, E,

and F, (see Fig. 5.) To the said disks l2 and 14 is also secured concentrically thereof a perforated cylinder 16 forming the inner walls of thecompartments. The disks 12 and 14 are provided with peripheral inwardly extending flanges 17 and 18 respectlvely to which perforated plates 19 are secured. These plates 19 alternate with perforated cover plates 20 and said plates 19 and 20 make up the outer rim of the Carrier. One plate 19 and cover plate. 20 serve as the outer wall of each compartment, and each cover plate is hinged at 21 to swing outwardly and is equipped with a suitable fastening means 22.

Fixed to the shaft 9 by means of set screws or other means 23, are flanged hubs 24 between which are secured circulating blades 25 radiating from the said shaft 9.

Fixed to the shaft. 9 by means of a set screw 29, is a sprocket wheel 30, and around this sprocket wheel passes a chain or other flexible belt 32. This chain or belt also passes around a smaller sprocket wheel 33, which wheel is rotatable with a drive pulley 34. This pulley 34 is journaled with a loose pulley 35 on a stub-shaft 36 extending from a plate 37 which latter is secured to one of the sides 2 of the vat. Also rotatable with the drive pulley 34- is a spur gear 38 which transmits motion to a similar gear 39 in mesh therewith and journaled on a stubshaft 40 parallel with the shaft 32. Journaled in bracket bearing 41 is a shaft 42 of gear 43, which gear 43 meshes with the said gear 39. On the end of the shaft 42 is fixed a pinion 44 which meshes with the gear portion 45 of the end disk 12 of the carrier. The said gear portion 45 constitutes a peripheral flange extending in an opposite direction to the flange 17 of the said disk 12.

In operation, power is applied by means of a belt, (not shown,) to the drive pulley 34 causing the same to rotate. The sprocket wheel 33 rotates therewith and through the medium of the chain 32 and sprocket wheel 30 causes the circulating means 25 to rotate in the direction of the arrow X. Motion is imparted from gear 38, which alsorotates with the pulley 34, through gears 39, 43, 44 and 45 to the carrier, rotating the carrier in the direction of the arrow Z. The carrier and circulating means rotate in opposite directions, the former more rapidly than the latter. The vat is filled with dye liquor to the level shown in Fig. The goods to be dyed are compacted into the compartments A, B, C, D, E and F, but left loose enough not to interfere with the free passage therethrough of the dye liquor, and the carrier and agitator set into motion. hen the compartment A is at the zone G, the compartments F, E and D are at the zones L, K, J respectively, and all submerged or partly so in the dye liquor. The agitators 25 rotating in the direction of the arrow X, draw the dye liquor through the compartment A from the exterior thereof to the center of the carrier as indicated by arrows; and from the center, the agitators force the dye liquor through the compartment D to the exterior of the carrier as indicated by arrows. The perforated walls of the compartments permit this circulation. Likewise, the agitators draw the dye liquor through the compartment F from the ex terior of the carrier to the center of the carrier; and force the dye liquor from the center of the carrier through the compartment E to the exterior of the carrier. This circulation of the dye liquor by the agitator is confined to the paths indicated by the end walls and partitions, which in the main should be imperforate. The dye liquor from the compartments A, B, C and D or the portions thereof not submerged drains into the central chamberof the carrier, except for a small portion that escapes through the exterior walls of the same. As the car- 'rier slowly rotates to bring the compartments F, E, D and C adjacent the zones Gr, L. K and J respectively, the dye liquor circulates from the carrier exterior through the compartments F and E to the carrier center, and from the carrier center through the compartments D and C to the carrier exterior. The dye liquor in the vat between the carrier and vat bottom flows continu ously in one direction from the zone J to the zone G. From the zones L and G, the dye liquor flows from the exterior of the carrier to the center thereof; and from the center thereof toward the zones J and K. Obviously at certain points the lines of flow will not be exactly as described and illustrated, as there will be certain eddy currents tending to break the direct flow at certain points, but in general the circulation of the dye liquor will be as described, and the bulk of the liquor will take the paths of flow indicated. At the zones L and G, the dye flows through the goods in one compartment in one direction. This dye liquor then drains from the said compartment as the latter leaves the vat, and as the compartment is again submerged at the zones J and K the dye liquor again flows through the goods, "but in a reverse direction. The carrier turns slowly so as not to roughen or tangle the goods in the compartments and to not interfere with the described circulation of the dye liquor. On every rotation of the carrier, the dye liquor passes twice through. the goods in the compartments, once in one direction and then in a reverse direction.

Of course it will be understood that the invention is not restricted to dyeing, but is applicable generally to impregnating such as washing, coating or otherwise.

The invention is particularly adaptable to treating knit goods, as stockings, but may be employed for treating any other goods 0 articles.

Whatis claimed is:

1. In a dyeing machine, the combination of a vat, a rotatable carrier therein having imperforate end walls, and means within the carrier for circulating the dye liquor through a portion of the carrierin one direction at one point in the travel of the carrier and in a reverse direction through the same portion of the carrier at another point in the travel of the carrier.

2. In a dyeing machine, the combination of a vat, a rotatable carrier therein, said carrier including walls forming a compartment with imperforate end walls to receive the articles to be dyed, and means within the carrier for circulating the dye liquor through the compartment in one direction when the carrier is in one position and through the compartment in a reverse direction when the carrier is in another position.

3. In a dyeing machine, the combination of a vat, a rotatable carrier therein, and rotating circulating means for the dye liquor located within the carrier, the carrier having perforated walls and imperforate end walls which cause the dye liquor to flow through a port-ion of the carrier in one direction when the carrier is in one position and to flow through the same portion in a reverse direction when the carrier is in another position.

at. In a dyeing machine, the combination of a vat, a rotatable carrier therein, the carrier including walls forming a compartment with imperforate end walls to receive the articles to be dyed, and rotating circulating means for the dye liquor located within the carrier for circulating the dye liquor through the compartment in one direction when the carrier is in one position and through the compartment in a reverse direc tion when the carrier is in another position.

5. In a dyeing machine, the combination of a vat for the dye liquor, a shaft, a cylindrical carrier thereon and being rotatable in the vat, a circulating means on the shaft comprising radial blades extending longitudinally of the shaft and being rotatable within the carrier oppositely thereto to circulate the liquor in one direction within the vat and y in a reverse direction radially through the carrier toward and from the axis thereof, the carrier rotating in the direction of the circulation of the liquor in the vat, said carrier comprising radial longitudinal partitions, imperforate end walls and perforated peripheral wall.

6. In a dyeing machine, the combination of a vat, a rotatable carrier therein, means 10 within the carrier for circulating the dye liquor in a current radially inward through one portion of the carrier and a current radially outward through another portion of the carrier, and means preventing mingling of the said currents while within the carrier. 15
